1) You are a very 'musical' person and have a good ear for melody.
2) You grew up listening to a lot of synth pop.
3) You also suffer from another condition called 'riff-itis' where for every bassline you program, you have a dozen catchy hooks to complement.
4) You love 80s instrumentals like Axel F.
The remedy:
House is all about the 'feel' and synergy. 1+1=11. A few well chosen parts work better than half a dozen average ones. Most house tracks don't have too much going on. Its all about clever programming, liberal filter sweeps, anticipation, rise and fall and always leaving them wanting more.
The key is to change your habits. Every time you have a melodic tendency, fight it. Every time you feel like sticking a bunch of nice little riffs in there, don't. Avoid riffs altogether, or stick to one if you must. Keep most things in the background and focus on the main element, whether it's the bass or the vocal. Avoid the tendency to fall back on your 'formula'. Do the 'opposite' of what you are inclined to do. Hey, it worked for George Costanza...
Or you could combine the two and make Progressive House. But why would you want to do that...
